PURPOSE: We investigated the direct labeling method of antibody with 99mTc and 188Re and examined the stability and function of these labeled compounds in in vitro and in vivo. MATERIALS AND METHODS: Disulfide bond of nonspecific human IgG was reduced to -SH group by 2-mercaptoethanol. Stannous ion was used to reduce 99mTc and 188Re. The stability of 99mTc-IgG and 188Re-IgG was estimated upto 24 hrs. Biodistribution was evaluated in abscess bearing rats at 4 and 24 hr post-injection of 99mTc or 188Re labeled IgG. RESULTS: The number of -SH group per reduced IgG molecule was 2.34. The labeling yield of 99mTc-IgG and 188Re-IgG were 90% and 95%, respectively. The stability of 99mTc-IgG at 1, 4, 6 and 24 hr was 91%, 83%, 78%, 7% and that of 188Re-IgG, high uptake was found on kidney, blood, stomach and abscess (9.42+/-0.68, 1.43+/-0.24, 0.86+/-0.18, 0.72+/-0.10 %ID/g, respectively). The uptakes at 24 hr were kidney, abscess, stomach, and blood in descending order. In case of 188Re-IgG, high uptake at 4 hr post injection appeared on kidney, blood, abscess and stomach (3.92+/-0.62, 1.32+/-0.08, 0.88+/-0.01, 0.26+/-0.06, respectively). The upatkes at 24 hr were kidney, abscess, blood abd stomach in descending order. The abscess to blood uptake ratio of 99mTc-IgG was 0.5 at 4 hr and 2.02 at 24 hr and that of 188Re-IgG was 0.67 and 1.29. CONCLUSION: 99mTc-IgG and 188Re-IgG and 188Re-IgG canbe labeled efficiently with direct labeling method. However, 99mTc-IgG and 188Re-IgG, labeled with direct method, was unstable. Further study in needed to enhance the stability of the antibody labeling.

PURPOSE: This study conducted an analysis of cost-effectiveness of the implant and conventional fixed dental prosthesis (CFDP) from a single treatment perspective. MATERIALS AND METHODS: The Markov model for cost-effectiveness analysis of the implant and CFDP was carried out over maximum 50 years. The probabilistic sensitivity analysis was performed by the 10,000 Monte-Carlo simulations, and cost-effectiveness acceptability curves (CEAC) were also presented. The results from meta-analysis studies were used to determine the survival rates and complication rates of the implant and CFDP. Data regarding the cost of each treatment method were collected from University Dental Hospital and Statistics Korea for 2013. Using the results of the patient satisfaction survey study, quality-adjusted prosthesis year (QAPY) of the implant and CFDP strategy was evaluated with annual discount rate. RESULTS: When only the direct cost was considered, implants were more cost-effective when the willingness to pay (WTP) was more than 10,000 won at 10th year after the treatment, and more cost-effective regardless of the WTP from 20th year after the prosthodontic treatment. When the indirect cost was added to the direct cost, implants were more cost-effective only when the WTP was more than 75,000 won at the 10th year after the prosthodontic treatment, more than 35,000 won at the 20th year after prosthodontic treatment. CONCLUSION: The CFDP was more cost-effective unless the WTP was more than 75,000 won at the 10th year after prosthodontic treatment. But the cost-effectivenss tendency changed from CFDP to implant as time passed.

PURPOSE: To investigate the characteristics of the waveform generated by blue and red light stimulations in a dark-adapted electroretinogram (ERG) and those of cone responses in the dark-adapted condition. METHODS: The study subjects were 52 persons (88 eyes) with no previous medical history. The author recorded b-waves (rod response) with red light stimulation and the x-waves (dark-adapted cone response) that appeared before the b-waves. The author also recorded b-waves with blue light stimulation, which had the same amplitude as the b-waves from the red light stimulation. The differences with respect to age and gender were studied. Waveforms of the dark-adapted cone ERGs were recorded by using a digital subtraction technique. RESULTS: The x-wave always appeared before the b-wave with 0 dB (2.4 cd.s/m2) red stimulation. With blue stimulation, a b-wave equivalent to the b-wave stimulated with the red light of 0 dB intensity appeared at an average of -14.57 dB. The implicit time for the b-wave was delayed significantly for the male group. There were no significant differences between different age groups. The dark-adapted cone ERG demonstrated the waveform of a negative response followed by a series of oscillatory potentials (OPs) and a positive response. CONCLUSIONS: The cone responses were followed by the rod responses with red light stimulation of 0 dB in the dark-adapted ERG. The waveforms of the cone ERGs were obtained in dark adaptation with red and blue light stimulation.

BACKGROUND: The dipyridamole and dobutamine stress echocardiography have been studied as a non-invasive diagnostic test in coronary artery disease. Recently, some authors have extended the usefulness of these tests to predicting the prognosis of myocardial infarction patients. But as far as we know, there was no literature which tried boh tests to the same infarcted patients group. So, we performed both tests in the 23 infarcted patients to compare and evaluate both tests as predicting the prognosis in myocardial infarction. METHODS: Patients underwent (1) two-dimensional echocardiography under basal condition and after dipyridamole infusion for 4 minites at the dose of 0.14mg/kg/min, (2) another two dimensional echocardiography under basal and during dobutamine infusion at each dose of 5 to a maximum of 20microg/kg/min at 1 or 2 days after dipyridamole stress echocardiography, and (3) coronary and left ventricular angiography. Preinfusion and peak infusion images were analyzed independently by two different observers using Nova Micro Sonic soft were(DataVueII and ColorVue II analysis system). The segmental wall motions were scored as follows ; hyperkinetic : 1, normal : 2, hypokinetic : 3, akinetic : 4. THe test response was considered positive if abnormal wall motion and reduced myocardial thickening were observed during drug infusion at the vascular distributions except the akinetic infarcted segment identified during basal condition. The coronary angiography was analyzed by measuring the maximal luminal diameter stenosis with caliper and 50% or greater diameter narrowing was considered significant. The sensitivity and specificity were calculated by comparing echocardiographic prediction and angiographic findings. RESULTS: 1) Among 22 patients with sufficient image in dipyridamole stress echocardiography, 13 patients have myltivessel coronary disease without resting akinesia of non-infarcted segments. Only 5 patients showed positive findings in dipyridamole stress echocardiography(sensitivity, 38.4%). Among 9 patients who has single or minimal disease, 9 patients were negative finding(specificity, 100%). 2) Among 21 patients with sufficient image in dobutamine stress echocardiography, 12 patients have multivessel coronary disease without resting akinesia of non-infarcted segments. 7 patients showed positive finding in dobutamine stress echocardiography(sensitivity, 58.3%). Among 9 patients who has single or minimal disease, 8 patients showed negative finding(specificity, 88.8%). 3) In hemodynamic changes, dipyridamole stress echocardiography showed significant changes in heart rates and double products and dobutamine stress echocardiography showed significant changes in heart rates, systolic blood pressure and double products. 4) There was no significant side effect during both stress tests inacute and old myocardial infarction patients. CONCLUSION: 1) The dobutamine and dipyridamole stress echocardiography are safe and easy test for myocardial infarction patients. 2) The dobutamine stress echocardiography has higher sensitivity than dipyrdamole stress echocardiography for identifying multivessel coronary disease in myocardial infarction patients but the dose of both drugs were relatively small to get the adequate results. So the high dose of drugs must be tried in feature study.

The purpose of this study is to observe histopathologic changes in the bilateral craniomandibular joints after allowing 6 weeks of consolidation by varying the amount of distraction in rabbit mandible. Eight rabbits weighing about 2 to 3kg were used. After corticotomy was performed on the left mandibular body between the first premolar and the second premolar region, a unilateral fixation device was placed. Then, a 7-day period was allowed without distraction of the device. The mandible was lengthened 0.5mm/day. Corticotomy and lengthening of mandible were not performed in control group. After the completion of the lengthening process, a 6-week-consolidation period was allowed. Then, the rabbits were sacrificed, and histologic examination of the craniomandibular joints was performed. Proliferative changes were observed in the craniomandibular joints in all groups. With the increasing amount of distraction, hypertrophy of the cartilage layer became more severe, bone formed was dense and enchondral ossification was clearly shown in subchondral bone. Hypertrophy of the cartilage layer was also seen in the non-distracted side as the distracted side in the experimental group. These results indicate that when physical force is applied constantly to joints, the proliferation of articular cartilage and bone formation are present. When more than 6 weeks of consolidation period is allowed at the time of performing distraction for more than 5mm, articular changes, especially, in the contralateral side should also be noted.
